In the video below, Motley Fool Stock Advisor associate advisor Alex Scherer explains why he thinks Interactive Brokers deserves a place in your portfolio. While Interactive Brokers goes head to head with a litany of brokerage services that includes E*TRADE (Nasdaq: ETFC), optionsExpress (Nasdaq: OXPS), and Charles Schwab (NYSE: SCHW), Scherer likes the niche the company targets. Specifically, while it has fewer trading accounts, Interactive Brokers has users who trade far more than other services, which delivers margins competitors can't touch.
